The fossil record is a joint expression of
Combine models of stratigraphy with evolutionary biology and ecology into stratigraphic paleobiology modeling pipelines
Focus:
Age-depth models and incompleteness
Trait evolution
Fossil abundance, ecology, and last occurrences

Traits are measurable characteristics of an organism
How do traits evolve in a lineage?
Stasis - no net change
Random walk - random accumulation of change
Ornstein-Uhlenbeck (OU) process - convergence towards an optimum
Plot the different modes of evolution in the time domain.
Transform the different modes of evolution into the stratigraphic domain and plot them.
Taxa track their preferred niche
Environmental conditions at a place change with time
How does ecology change fossil abundance?
How does stratigraphy influence extinction rate estimates?
